Subject: [PATCH 2/2] ARM: shmobile: silk: add SDHI0/1 DT support
Date: Sun, 22 Feb 2015 01:27:42 +0300 [thread overview]
Message-ID: <2348421.LHyZ4ZOiiG@wasted.cogentembedded.com> (raw)
In-Reply-To: <10037494.4LD4T2QGPX@wasted.cogentembedded.com>
Define the SILK board dependent parts of the SDHI0 (connected to SDIO Wi-Fi
chip) and SDHI1 (connected to micro-SD slot) device nodes along with the
necessary voltage regulators.
Based on the original patch by Vladimir Barinov
<vladimir.barinov@cogentembedded.com>.
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>
